Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to linen sagrai laundry, such as sheets,
Linen sorting equipment that automatically sorts items such as wraps, pillowcases, shacks, towels, towels, uniforms, and mats is concerned.

[Conventional technology]

Conventionally, there has been no device that automatically sorts linen sagrai laundry (hereinafter referred to as linen), and it has relied solely on manual labor.

That is, when used and dirty linen received from a customer is delivered, various items are mixed together in a bag or container.

Therefore, workers had to manually sort the linen in each tank and put the same type of linen together into a tunnel washing machine or the like.

[Problem that the invention seeks to solve]

Conventional sorting requires manual labor, which is not only labor intensive but also unhygienic, and it is also difficult to control the amount of goods received.

Therefore, it is an object of the present invention to provide a linen sorting device that can automatically sort linen without human intervention, reduces labor, is hygienic, and also facilitates the management of the amount of incoming goods. shall be.

[Means for solving problems]

The present invention is characterized by taking the following measures in order to solve the above problems and achieve the objects. That is,
A single linen is taken out one by one from a linen mass containing multiple linens and transported continuously, and in the process of transport, at least three factors are determined: ``linen hanging length'', ``linen weight'', and ``linen color''. K to detect type information.

Then, the type of the single linen is determined based on the detected information, and automatic sorting is performed according to the result of the first determination.

[Effect]

By taking such measures, the linen can be sorted automatically and accurately.

〔Example〕

FIG. 1 shows the configuration of a control system according to an embodiment of the present invention.
It is a diagram! FIG. 2 is a schematic side view showing the configuration of the mechanical system. As shown in FIGS. 1 and 2, a linen hanging length detector 1, a weight measuring device 2, a color detector 3, and a metal detector 4 are arranged along the conveyance route of the conveyor 6. Each piece of detection information is supplied to the control device 5.

The linen hanging length detector 1 is constructed by vertically arranging a plurality of photoelectric sensors, limit switches, touch sensors, etc. near the starting end of the conveyor 6. It is used to detect length.

The weight measuring device 2 is provided to be able to measure the weight of a single piece of linen 8 that has been transported, and is of a ronid cell type or a spring type.

Color detector 3 is a color sensor configured to optically detect the color of a single piece of linen 8.

The metal detector 4 detects a metal recognition piece sewn onto the linen 8 when it is difficult to identify the linen 8 using only information such as hanging length, weight, color, etc. There are nine types that utilize electromagnetic induction. The size, shape, and shape of the metal recognition pieces are determined according to the type of linen 8.
It is made of materials, etc., and is set in advance so that induced currents of different magnitudes flow due to the 11E magnetic induction effect.

When the control device 5 is supplied with the information detected in steps 1 to 4 above, it stores this information in the data memory, performs processing such as comparative judgment, determines the type of linen 8, and sends the sorting command. It is intended to send out. That is, this control device 5 is configured mainly with a central control device 51, and each device 52 to 55 of this central control device 5111C is connected.

The sensor data storage device 52 stores the hanging length detectors 1-
It is a device that stores information from the metal detector 4, that is, sensor data, when it is given through the central control device e51.

The sorting standard setting device 54 is a device that sets standard data for determining linen items W1 in advance.

The type discrimination device fj153 compares the data stored in the sensor data storage device 52 provided via the center control device 51 and the standard data set by the standard setting device 54 for sorting, and determines the type of each linen. It is a device that makes a distinction.

The display device 55 is a device that displays data such as the number of sheets by type and the total number of sheets sorted based on the data from the devices i152 and 5J.

The control device 5 is equipped with a command device 1 (not shown) for sorting, and as shown by the arrow, a command signal S is sent out for sorting according to the determined linen type, and when the linen reaches the end of the conveyor 6. The linens 8 are automatically sorted by a machine (not shown).

By the way, the conveyor 6 is a hanging type conveyor equipped with a hanging tool 7, and conveys a single piece of linen 8 as shown by a thick arrow.

A single piece of linen 8 has been removed by a linen remover 9 and loaded onto the conveyor 6.

The linen take-out machine 9 is equipped with a chuck 10 at the end of the arm, and a chuck 10 takes out any one piece from a linen lump 11 containing a mixture of multiple types of linen, and hangs it on the compare 6. A single piece of linen 8 can be loaded by hanging it on a lowering device.

Next, the operation of the apparatus constructed as described above will be explained with reference to FIGS. 3 and 4.

The hanging length of the single linen 8 taken out by the linen takeout WA9 and delivered to the hanging tool 7 of the conveyor 6 is:
Must be within a certain length range. For example, if the taken out single linen 8 is a rectangular cloth as shown in FIG. 3 (1),
The maximum length is the diagonal length t when gripping point A as shown in Figure 3 (b), and the shortest length is half the diagonal length t when gripping the center point 0 as shown in Figure 3 (, ). The self length is 1/2 t.

Even in the case of irregularly shaped clothing such as a yukata, the hanging length is within a certain range of lengths. If it is necessary to detect the hanging length with higher accuracy, please use the method shown in Figure 4 (,
) to (, ), by gripping the single linen 8 taken out by the linen take-out machine 9 again, it is possible to easily grip the end that has the maximum length.

That is, suppose that when a single piece of linen 8fWcl made of rectangular cloth is first gripped by the chuck 10 as shown in FIG. 4(a), an arbitrary point P is gripped as shown in FIG. 4(b).

At this time, the lowest point of the hanging linen 8 is point A at one corner of the rectangular cloth. So I put the second chuck IOB on,
As shown in FIG. 3(c), grasp the lowest point, i.e. point h, again. By doing this, the single linen 8 will be hung at the maximum hanging length.

In this way, the hanging length of the single linen 8 suspended within a certain range of hanging lengths is detected by the hanging length detector 1. Information is transmitted to control bag Wt5. - When the single linen 8 is transported by the weight measuring device 2t, its weight is measured here. The above weight varies depending on the moisture content of the linen 8. In extreme cases, it can reach several times its weight when completely dry. However, since there is usually a significant difference in the basic weight of a single linen 8 based on its type, discrimination is possible. Furthermore, in order to detect the weight with high accuracy, it is desirable to dry it by some kind of drying means to keep the moisture content constant before measuring the weight.The measured weight information is transmitted to the control device 5. Ru.

When the single linen 8 is conveyed to the color detector 3, it is detected here which of the four color systems white, yellow, red, and blue it belongs to, and this information is transmitted to the control device 5. be done.

When the single linen 8 is conveyed to the metal detector 4 position #L, a metal recognition piece is sewn onto the single linen 8 and information such as whether it is present, its size, force 1, etc. is detected. is,
It is transmitted to the control device 5. Therefore, accurate information can be obtained in cases such as when a single piece of linen 8 is "patterned" and it is difficult to distinguish the color, or when the linen 8 is of the same type and requires special sorting.

Each piece of information transmitted to the control bag @S is stored in the sensor data storage device 52, and all or part of the stored data is sorted using the standard data set by the standard setting device 54 and the type discrimination device 53. be judged comparatively. As a result, the type of single linen 8 is determined and classification is performed.

Note that in the control device 5, the number of sheets of the same type of linen 8 is counted and displayed on the display device 55, so that the arrival management can be performed accurately.

"Experiment example" Five types of towels were prepared as shown in Table 1.

Further, for sorting in the control device 5, standard data as shown in Table 2 is set using a standard setting device (ILS4).

In Table 2, regarding the hanging length, data was set to be divided into two categories based on 75cy1, taking into consideration the array length of the photoelectric sensor. In addition, regarding weight, 22011 is the standard in relation to the load cell type weight check and car.
The data to be classified has been set. Furthermore, regarding color, we have set data that categorizes the color into two categories, ``yellow'' and ``blue,'' depending on the brightness difference detected by the color sensor. Regarding metal recognition pieces, we have set data to classify them into two categories: presence and absence.

After making these preparations, 5 types of towels■
-■ were arbitrarily selected and conveyed by the conveyor 6, and the sorting function was checked, and the following results were obtained.

■Towels have a hanging length of 75 meters or less and a weight of 2.
It was 20 years or less in length, blue in color, and had a metal recognition piece attached, so it was determined that it was a ``■'' towel, and it was possible to sort it.

The towel (■) had the same length, weight, and color as ■, but because it did not have a metal recognition piece attached, it was determined that it was the towel (■), and it was possible to sort it.

The length, weight, and recognition piece of the towel marked ■ are the same as the towel marked ■, but the color is yellowish, so it was determined that it was the towel marked ■, and it was impossible to sort it.

The towel (■) had the same length, color, and recognition piece as (2), but the weight was 2201 or more, so it was identified as the towel (■) and could be sorted.

The towel in ■ is the same as the towel in ■ in terms of weight, color, and recognition piece, but since the hanging length is 753 or more, it was identified as the towel in ■ and was able to be sorted. .

In this way, according to one apparatus, the type of linen 8 is automatically determined and the discharge destination of the conveyor 6 is automatically designated, so that the linen 8 can be automatically sorted. Also, the linen is conveyed one by one as a single linen 8.
Since the paper is conveyed by the paper and the information is detected, the number of paper sheets of each type can be counted and displayed at the same time.

As a result, large amounts of linen received from customers such as hotels can be automatically and accurately sorted, and the number of sheets can also be confirmed, making inventory management and next day's operation planning more accurate. Not only can this be done, but it is also effective in avoiding trouble with customers.

〔Effect of the invention〕

According to the present invention, linen can be automatically sorted without human intervention, reducing the labor of the worker, and
We can provide a linen sorting device that is good for hygiene and also makes it easier to manage the amount of incoming goods.
